"I have known Tim for over 20 years, he was the most brilliant and most careful severe weather researcher of them all. Tim was not a cowboy, he was as cautious as possible about his approach to studying these dangerous storms."

"My condolences go to all of the family and friends of Tim Samaras, Paul Samaras, and Carl Young. I hope that their deaths will lead towards safer tornado chasing, and help spur efforts to use emerging drone technology to take measurements in dangerous storms such as tornadoes and hurricanes."
